Andrew took a random sample of 10 decorated ceramic cups from a population of 100 cups. barbara took another random sample of 10 cups from the same population for the same task. what would happen if andrew and barbara both choose a sample size of 20? the difference of their sample means is likely to .. a. remain the same b. increase c. decrease
i think the answer is increase because:
10 divide by 100 = 0.1
10 divided by 90 = 0.1
but 20 divided by 100 = 0.2
and 20 divided by 80= 0.25
here the give expression is,
we can write,
( because )
⇒ option d is correct.
graph one would be alternate exterior.
graph two would be corresponding.
graph three would be alternate exterior.
graph four would be alternate interior
and lastly, graph five would be corresponding.
and to follow what direction i went, i started from left to right.
